Model Selection of Durometer
As to measured
value by
durometer
(robber and
plastic
hardness
tester), when
the base of
durometer and
work piece are
cohered each other, the indentor changes shape of
work piece by pressurized force caused by spring of
durometer and work piece makes force against this
force. Force amount of indentor is indicated as
hardness when this pressurized force and repulsive
force are equivalent.
If repulsive force is weak, it shows low value (soft), on
the contrary, if repulsive force is strong, it shows high
value (hard). There are various type of durometers of
which force of springs and shape of indentors are
different. The reason why there are various kinds of
durometers, it is for the purpose of showing degree of
hardness with higher sensitivity against difference of
material characteristics and shape of surface which
work pieces have. Select a suitable product referring
to the figure in the right.

As to measuring hardness by pushing by
hand, durometer to work piece form the top
and read value by making pressed surface
adhere to durometer.
In order to solve individual difference of
measured value, it is clearly mentioned in
the standard to measure hardness by
mounting durometer to stand.
Measuring hardness with Durometer
1. In case of measuring by pushing by hand, putting pressurized
surface of durometer held by hand from the top vertically with a
certain speed to the flat face of work piece which is put on the flat
face . Then, after adhering it, regard the value measured within the
passed time prescribed by standard as “hardness”.
2. In case of measuring hardness by mounting durometer to stand,
measuring speed (not more than 3.2mm/sec.), pressurized load
(type A, E is 1kgf, type D is 5kgf) and pressurized surface diameter
(φ18mm) of type A / D durometers including tolerance are
standardized.
3. Measuring point of test piece is to be inside from its edge by 12mm
or more and clearance is to be 6mm and more. Thickness is
normally 6mm and more, and 10mm and more for type E.
4. Test environment : Temperature is 23℃±2, humidity is 50±5% and
median or average is applied for measured value. If 50 show in type
A case, it is described［A50］.
These are ruled for each standard.

Durometer & IRHD Hardness Tester
Durometers show the degree of hardness by value whether a non-rigid material like rubber is soft or hard (hardness gauge for rubber or plastic).
Recently, JIS standard and ISO standard have been drastically revised and details of hardness tester of rubber and method of measuring
hardness are changed.
As an all embracing manufacturer of non-rigid material hardness tester, Teclock proposes lots of measuring methods of measuring hardness of
not only rubber and plastic but many non-rigid materials and elastic materials.

Durometer
59
This is Durometer to comply with JIS K 6253 (new JIS) standard established in 1993 for the purpose of conforming to ISO (International Standard
Organization). Durometrers consist of 3 types namely, Type A for medium hardness, Type D for high hardness and Type E for low hardness.
Type A tends to indicates higher value by 1~2 points compared with former Type A durometers. Type D is suitable for hard rubber having more
than 90 hardness measured by type A durometer and Type E is suitable for soft rubber of which hardness is 20 and below measured by Type A
durometers.
Pressurized face diameter of type A and
type D durometer mounted to a stand is
defined 18mm by JIS standard and ISO
standard. φ18mm type A(GS-719R) and
type D (GS-720R) can be used as they are
for measuring by pushing by hand.

This is the model for which peak hold (Maximum value is held)
function is mounted.
This is effective to measure hardness of Elastomer of which
maximum value is unreadable due to relaxation phenomenon.
Minimum read value is o.5 and it is a half of analog type.
Measured data can be treated as statistics by connecting with
optional printer SD-763P.

Peak Pointer Type
Some of Rubbers, Elastomer' elastic body is not easily read the maximum value after firm contacting
with a presser foot of durometer , due to the stress relaxation. The pointer indicates the descendent
value but the peak pointer is holding the maximum measured value. The peak pointer type can easily
read the maximum value efficiently. In case the pointer cannot be read directly due to some obstacles
altough the measuring can be done, the mesured value can be confirmed from peak pointer after
measuring. The upper / lower limiters equipped will be effectively used in tolerance judgment.

Deep Hole / Long Leg Type
In some cases, such as the measurement surface of uneven or with a narrow flat area and the bottom of deep hollow, it may be impossible to
achieve the proper results because of the difficult contact of the presser foot. The Deep Hole (H) type and the Long Leg (L) type make such
measurements possible with a small or long presser foot. Both are supplied with Peak Pointer and the upper/lower limiters. The Long Leg type
meets also to DIN 53505 standard.

This standard is prescribed by plastic industry in Japan apart from testing method of hardness of rubber. This is basically equal to Durometer of
JIS K 6253, as only its round up method of spring load value etc. is different. But we distinguish model name as another Durometer according to
the view of conformity to standard.

JIS K 6301 was established in 1950 and had sustained base of
rubber industry of our country but was discontinued in 1998
because it did not comply with ISO and also JIS K 6253 was
prescribed on its behalf. However, It had been used for 60 years as
“Rubber hardness tester” and even now it is used as test data
between certain parties in charge with mutual consensus although
movement to new JIS has progressed and standard is discontinued.
There are 2 models such as Spring type A and type C for hard

E durometer as they are. Measuring by
type D needs optional weight ZY-046 for
measuring 5kg.. Digital durometer GSD
series needs optional weight ZY-090 for
measuring 1kg..
●Calibration certificate can be issued.
●Hardness can be measured by durometer
with load prescribed by JIS by mounting
durometer and manual operation.
●Adopting cam has realized easy
operation and cost performance.
●Alignment unit which realizes high
contact between indenter (contact point)
of durometer and test piece is mounted.
●1kg can be measured by type A and type
E durometer.as they are. Measuring by

measuring 5kg.. Digital durometer GSD
series needs optional weight ZY-079 for
measuring 1kg..
●Calibration certificate can be issued
(Operation speed certificate can not be
issued.).
●Speed controller with high reliability is
adopted for moving down speed adjustment
unit.
●Alignment unit which realizes high contact
between indenter (contact point) of
durometer and test piece is mounted.
●65mm for analog and 40mm for digital are
obtained for possible measuring range.
●Shaft with square thread is adopted that can
prevent holder falling down and moving up
and down.
●1kg can be measured by type A and type E
durometer as they are. Measuring by type D
needs optional weight ZY-046 for measuring
5kg.. Digital durometer GSD series needs
optional weight ZY-090 for measuring 1kg..

Durometer Periodical Inspection / Calibration
Durometer is a testing machine. In case that it corresponds to “Monitoring Machine ” and “Measuring Machine” of ISO 9001 (JIS G 9001),
controlling machines along with it is needed. Teclock is one of a few manufacturers of durometer which has obtained the authentication of ISO
9001 and can originally issue 3 kinds of traceability system diagram, calibration certificate and inspection report that are needed for calibration
documents. In addition, Teclock can issue 3 kinds of documents for durometer tester and indentor height gauge, that are needed for internal
inspection. Use these for control based on internal calibration standard.
This is inspection machine which simply checks spring load value of analog type durometer. Putting defined
load with 3 pieces of standard weight to the inverted durometer and inspecting whether graduation of 25,
50 and 75 correctly point out. Calibration certificate can be issued. (Digital type durometer and other makes
products can not be calibrated.)
In addition, in the standard of overseas and also domestic, inspection method by using mechanism of even
balance and with normal position of durometer is introduced.

It is the comparison list of measured data by each durometer based on type A. As hardness values fluctuate owing to various factors
temperature and humidity on measuring, dimension and shape, and vulcanizing condition in a certain range, it is impossible to verify complete
relative relation between each type. However, refer to the list in right side for comparison value.
Comparison of Measured Value by Durometer
There is a case that durometers correspond to “Monitoring Machine ” and “Measuring Machine” of ISO 9001.
Teclock has obtained the authentication of ISO 9001 and can originally issue 3 kinds of traceability system
diagram, calibration certificate and inspection report.
Calibration certificate can be issued to all Teclock durometers.

Precautions on use of Durometer (Rubber / Plastic hardness measurement)
1.Confirmation of performance
Please confirm requested standard and type of durometer on the occasion of receiving.
Please refer to the standard of JIS K 6253, K 7215, K 6301, ISO 7619, ISO 868 and ASTM
D 2240 in detail.
2. Test environment
(1) Test environment for measuring samples is prescribed at internal and external standard
as " 23±2℃､humidity 50±5%".
(2) please avoid using it where dust and oil mist attach to it.
3. Precaution on use
(1) Check before using
① Confirm whether operation is smooth.
② Confirm whether accretion is on pressurized surface or indentor.
③ Confirm whether the indicator indicates "0 point".)
(2) Never disassemble device and loose screws.
(3) Do not give the products any shock by being dropped or excessive load.
(4) Keep the products away from direct sun light, excessive high or low temperature, and high humidity or dust. Avoid using and storing the
products under the circumstances of water or oil.
(5) Do not press the products to hard samples like glass or metals excepting for the purpose of checkup and inspection.
(6) Do not clean with organic detergent ( thinner or benzine ) and not put oil onto the products.
(7) Do not apply a load to the indentor in right angle. Do not hit the products with a hard item.
4. Maintenance
(1) In case that outer dial can not be read due to dirt of crystal, please wipe stains from the crystal by using a dry cloth or a cloth dampened
with neutral detergent.
(2) In case that some sort of defect is observed for indicator, indentor and spring load value by check up and repair or adjustment is needed,
please inform the sales outlet where the products are bought. Products repaired or adjusted by parties not authorized by TECLOCK can not
be warranted by us.
5.Periodical inspection
Durometers are needed to be inspected during a certain period, which depends on usage frequency. Especially, in case that instruments are
controlled by "inspection, measuring and test instruments " of ISO 9000 series, it is important element.
(1)Indentor height : Indicator should indicate 0 on free condition. Then it is checked whether indicator is in 100 by pressing pressurized surface
onto hard and flat and smooth surface. Meanwhile, be careful so that indentor edge shape of Type D durometer is not changed.
(2)Indentor shape : It is checked by measuring microscope whether dimension and shape of indentor edge is in the permissible value of
standard. In case that there is abrasion or damage , indentor needed to be changed.
(3)Spring force : It is checked by giving load against each indicated value whether indicator correctly indicates. Please use durometer tester
"GS-607 series" to check load of ● mark check point of 25, 50 and 75 on outer dial. Permissible error of indicated value is ± 1.
